New release of LLM adds support for reasoning traces, OpenAI Responses, server-side tools, and smarter logging
simonwillison.net
I released LLM 0.32 this morning, the most significant new version of LLM since the initial launch of the project. The new version includes support for visible reasoning traces, server-side provider tools, redesigned content-addressable SQLite logs, new models, and new features enabled by the OpenAI Responses API. I also released a new version of the llm-anthropic plugin with substantial updates of its own.

Who knows how reality will continue to develop? There’s no way to prepare. When you can’t be prepared, be prepared to find poetry in the chaos. Secret messages, serendipitous grace, lines of meaning in a whirlwind of uncertainty.

Please help if you can:
I am working with some students who are studying programmers’ beliefs about software engineering folklore.
If you can spare a few minutes to answer the question in https://survey.bth.se/survey/2545 ,
we would be very grateful.
We would also be grateful if you could circulate the survey link to colleagues and friends,
since we would like to reach as diverse a demographic as possible.
Thanks in advance. Please help if you can:

On May 20, 2026, OpenAI made an announcement that shook the mathematical world. An internal AI model — one not available to the public — had come up with a counterexample to the “unit distance” problem, a conjecture made in 1946 by Paul Erdős, the prolific, itinerant Hungarian mathematician. Erdős posed thousands of questions, but this one was special: It was both simple to explain and…

Marcus Hutter —oldheads will remember him from AIXI —recently
published a book: Job-Less Utopia: Macroeconomics in the Age of
AGI . I’m always curious what the people building AI think or want the
future to look like, and I’m also always looking for non-doomer takes on the
post-AGI future, so I decided to read it and review it.
The first thing to say is that nearly every sentence is written by AI. To his
credit, Hutter says so plainly:

Our Moon is two-faced. Science missions unravel its layers.
jatan.spaceIt wasn’t until 1959 that any being on Earth saw our Moon’s farside for the first time. Because the Moon is tidally locked to Earth, we only ever see its familiar nearside face. In the early days of space exploration, the Soviet Luna 3 and spacecraft succeeding it transmitted the first lunar farside images . While these captured images at low resolutions by today’s standards, the photos nevertheless revealed a far more cratered hemisphere than the Moon’s nearside. It looked more akin ...

Engineers often complain that visibility should be their manager’s job. In other words, they think engineers should be able to focus on the code, while their manager figures out who’s doing well and rewards them.
This attitude is an extension of the “school fantasy”: the idea that your workplace should operate by the same rules as your school or university. After all, you didn’t have to worry about “visibility” during your education. You simply did the assignments and tests you w...

Bankrate counted 27% of US adults with a side hustle in June 2025, the lowest reading in its series since 2017. Intuit QuickBooks, asking a wider question six months later, counted 47%. Four recent surveys disagree on participation by 20 points and agree on nearly everything else. Below: what each one measured, and the earnings, hours and burnout figures behind the headline numbers.

ZFS includes inline compression, meaning files are compressed and decompressed on the fly. While you might expect this to reduce IO performance, it’s been proven to improve throughput by reducing the amount of expensive reads required, especially on older spinning drives.
Inline compression is wonderful. I don’t need to rotate logs to compressed files. I can temporarily expand virtual disks to raw images without taking up the entire maximum space of the disk. It’s also great for thwart...
I was at one of the local museums last weekend, because it was the last day of their exhibit on "clouds in art", that I'd been wanting to check out since March.
At the museum, I took pictures using a kids camera that instantly prints on thermal paper. I got this because Max had one at IWC Nürnberg and I thought it was cool — he also has a cool post about a thermal printer camera project , you should check that out.
It turned off before I got through the whole exhibit because it was ...
About two months ago, I discussed my fitness challenge where the goal was to get below 85.3kg, the oldest measurement I have on record on the scale’s app, starting from 89.6kg. We’re halfway through this challenge, and things got a bit out of hand because, as it’s often the case, I tend to go a bit extreme when I set this type of goal. I hopped on the scale this morning and logged an 81.1kg, which is the lowest weight I have on record since I bought the scale 10 years ago.

Remember me?
It’s been a while, I know. My last blog post went up here on February 19. The posts that came after were made by my mighty minions. I am lucky enough to have a great staff of assistants… though even with their help, I kept falling further and further behind.
This year has been… stressful, to say the least. So much has been happening, it’s been overwhelming. Some great things, exciting things. Dreams coming true. But there have been nightmares too. ...
I was watching a Jeopardy from 2004 (The Game Show Channel is rerunning Ken Jennings streak) and the following question raises a good question. The contestants where Ken, Jerry, Jennifer. In Double Jeopardy there was a category Biblical Name The Same. The clue was three last names (e.g., Driver, Sandler, West ) and the correct response is a biblical name that is the first name of people with that last name ( Adam : Adam Driver, Adam Sandler, Adam West). What happened with Biblical Name The ...

There’s been a fair bit of publicity of the Open AI “rogue agent” that hacked into Hugging Face . This prompted Anthropic to check what their models were up to and, to my complete lack of surprise, discovered three incidents where models had gained unauthorized access to data in other organizations. Simon Wilison concluded :
It’s abundantly clear now that running evals of cyberattack potential in models is a spectacularly risky business. Every AI lab needs to pay attention to ...

I wrote ryg_rans in 2014. I still regularly get questions and patch submissions from people who want to use it as a library. That is not what it’s for!
ryg_rans is not a library, never was. It’s a toy implementation of an algorithm whose core fits in something like 20 lines of code. It’s the equivalent of the wooden board you sometimes see in hardware stores where they have 30 different types and sizes of fasteners screwed, bolted or nailed in. The idea is not that you should use th...
In Physics simulations or game engines it’s sometimes useful to
determine the speed with which two objects are approaching each other.
This post will discuss the concept of closing speed , which is the
normal component of the relative velocity of two objects.
Relative velocity and its components
Suppose we have objects A and B [1] with velocity vectors
\vec{V_A} and \vec{V_B} . The relative velocity of B
w.r.t. A is:
\[\vec{V}_{B|A}=\vec{V}_B-\vec{V}_A\]

C++26 adds a new container to the standard library: std::hive . It is meant to occupy the ground between std::vector and std::list . Like a vector, it keeps its elements in contiguous blocks of memory, so scanning it does not require you to chase a pointer for every element. Like a list, it never moves an element once it has been inserted: your pointers, references and iterators stay valid, and you may erase any element in constant time without disturbing the others.
Internally, a hive is ...

During the heyday of AT&T, it was often said that the telephone system was the
largest machine ever built. The "hello machine" certainly was vast, but whether
or not you consider it to be a single machine raises challenging questions of
definition. The Internet, I think we can all agree, is not a single machine but
a system of interconnected ones. The telephone network, though, felt a lot more
like one device. "One Policy, One System, Universal Service" was once the slogan
of AT&T, a message tha...
